NOMAD is an experiment searching for ; (e) oscillations in the CERN Wide Band Neutrino Beam. After its completion (August 1995), the detector has performed according to expectations and has been taking data since. A preliminary analysis, based upon the event sample collected in 1995, saw no evidence for oscillations, thus setting an upper limit in the mixing angle for high m 2
We discuss constraints on the right-handed Majorana mass scale MR of the SUSY see-saw model in the mSUGRA framework. The sensitivity of radiative lepton-flavor violating decays on MR is compared with the reach in lepton-flavor violating channels at a future linear collider.
During a seminar several years ago, a participant asked if I could offer a tool that would help him manage physician relations at his hospital. Seeing this question as an opportunity for a class dialogue, I asked participants, “What is the first image that comes to mind when you hear the word ‘tool’?” The majority replied “hammer.” A few shouted, “gun” or “machine gun.” One even bellowed “chain...
If yon were to talk to Albert for a short time and hear him tell of his toys or his games with his friends, or of his trip to Cuba you would probably say, '' Here is a superior child or at least a boy who is better than average." Or if you were to judge him by his appearance and general manner you would probably say that he was a normal boy of ten with a pleasing personality and winning ways. H...
Infants begin to help other individuals in the second year of life. However, it is still unclear whether early helping behavior is based on an understanding of other individuals' needs and is thus motivated prosocially. In the present eye-tracking study, 9- to 18-month-old infants (N= 71) saw a character in need of help, unable to reach its goal because of an obstacle, and a second character th...
A review of the principles and applications of surface acoustic wave (SAW) devices is given. An implementation of a design method for SAW devices using MATLAB is described. Results of a comparison between the proposed simulation technique and experimental test results are
Refractor ambiguities are big problem in seismic refraction method especially in seismic engineering. There can be hidden subsurface geological phenomena such as hidden faults and shear zones which are not simply predicted by the travel-time graph or some geophysical methods. Head wave amplitudes are used to show the resolution of refractor ambiguities and the existence of anisotropy in complex...
Acoustic waves based MEMS devices offer a promising technology platform for a wide range of applications due to their high sensitivity and the capability to operate wirelessly. These devices utilize an acoustic wave propagating through or on the surface of a piezoelectric material, as its sensing mechanism. Any variations to the characteristics of the propagation path affect the velocity or amp...
Acoustic wave propagates properly in water, whilst most forms of electromagnetic waves, particularly in salty and dense sea water, are attenuated after a few tens or hundreds of meters so that it will be impossible to trace and detect them. This paper presents a special method for recognizing probable underwater currents, and reconstruction of their intensities, widths, and directions by usin...
In 2 studies we examined whether trait dissociation is related to spontaneous commission errors (reports of events that did not occur) in free recall of emotional events. We also explored whether the functional locus of the dissociation-commission link is related to repeated retrieval or shallow encoding. In Experiment 1 participants were exposed to a staged incident and were repeatedly asked t...
